Abstract

A method for operating a technical system, an apparatus and method for determining a movement profile, control apparatus and the actual technical system that includes at least one drive to move at least one axis, wherein at least one optimized movement profile of the axis is calculated with the aid of an optimization method that calculates an optimized movement profile with reference to preset points of a movement profile and/or preset regions of the movement profile, where for simplified and particularly understandable use, the optimization method includes physical boundary conditions from the start of the optimization method, where the use and initialization of the technical system by the user is made more understandable, for example, and where the optimized movement profile is used to control the at least one drive of the technical system.
